What is the difference between 5w 20 and 5w 30

Is there any big and significant variation between 5w 20 and 5w 30

Yes, 5W-20 and 5W-30 oils differ mainly in viscosity at operating temperatures. 5W-20 is thinner, enhancing fuel efficiency, while 5W-30 provides better protection under heavier loads and higher temperatures. Always use the oil your vehicle manufacturer recommends to avoid affecting engine performance and voiding warranties.

5w20 oil is thinner when your car is running, while 5w30 oil is thicker when it’s running. Most car makers are making engines that work with 5w20 oil. It’s important to use this type and not switch to 5w30.

5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperature

Key Differences Between 5W-20 and 5W-30 Oils:

  • Weight: 5W-20 is lighter and thinner than 5W-30.
  • Viscosity: 5W-30 has higher viscosity, providing thicker lubrication, while 5W-20 flows more easily.
  • Performance: 5W-30 performs better in high temperatures, while 5W-20 is preferable for lower buildup and faster flow.
  • Efficiency: 5W-20 offers higher fuel efficiency due to its easier flow, though 5W-30 remains a good option.
  • Temperature: Both oils have similar viscosity during cold starts, but 5W-20 flows faster, offering quicker lubrication.
